The Predictors Of Re-Bleeding In Chronic Liver Disease Patients After Endoscopic Variceal Band Ligation.

Background: Variceal bleeding is a key and most fatal complication observed in chronic liver disease patients with portal hypertension and is a major contributor to the high morbidity and mortality seen in these patients. Exploring the predictors of rebleeding in chronic liver disease patients is of paramount importance to alter disease course and impact on morbidity and mortality.

Methods: About 50 patients with chronic liver disease who previously had evidence of varices on upper GI endoscopy and had at least one episode of rebleeding after EVBL were included in this study.

Thermoluminescence (TL), kinetic parameters and dosimetric features of Pakistani limestone.

Thermoluminescence (TL), kinetic parameters and dosimetric features of Pakistani limestone (CaCO) is reported in this study. Both compositional and structural analyses reveal that the material has a crystalline nature with rhombohedral structure and non-uniform crystallite size having major content of CaCO. A powdered limestone sample of 30 mg is found to be the optimized weight for TL and other dosimetric studies.

Aerogelation of Polymer-Coated Photoluminescent, Plasmonic, and Magnetic Nanoparticles for Biosensing Applications.

Macroscopic materials with nanoscopic properties have recently been synthesized by self-assembling defined nanoparticles to form self-supported networks, so-called aerogels. Motivated by the promising properties of this class of materials, the search for versatile routes toward the controlled assembly of presynthesized nanoparticles into such ultralight macroscopic materials has become a great interest. Overcoating procedures of colloidal nanoparticles with polymers offer versatile means to produce aerogels from nanoparticles, regardless of their size, shape, or properties while retaining their original characteristics.

The psychological impact of COVID-19 on healthcare workers in Pakistan.

Introduction: The COVID-19 pandemic has challenged healthcare facilities and healthcare professionals' stamina and wellbeing. This study examines the psychological impact of COVID-19 on healthcare professionals.

Methods: This analytical cross-sectional study was conducted in July 2020 after institutional review board approval at a tertiary care institution in Lahore, Pakistan.

The Role of Ligands in the Chemical Synthesis and Applications of Inorganic Nanoparticles.

The design of nanoparticles is critical for their efficient use in many applications ranging from biomedicine to sensing and energy. While shape and size are responsible for the properties of the inorganic nanoparticle core, the choice of ligands is of utmost importance for the colloidal stability and function of the nanoparticles. Moreover, the selection of ligands employed in nanoparticle synthesis can determine their final size and shape.

A Case of Vogt-Koyanagi-Harada Syndrome Mimicking Optic Neuritis.

Vogt-Koyanagi-Harada syndrome is a rare disease that occurs commonly in pigmented individuals of Asian origin. A 25-year female presented in medical outpatient department (OPD) of Al-Khidmat Teaching Hospital, Mansoora, Lahore with headache and neck stiffness. She was referred to eye OPD for the complaint of decreased vision.

Quantitative uptake of colloidal particles by cell cultures.

The use of nanotechnologies involving nano- and microparticles has increased tremendously in the recent past. There are various beneficial characteristics that make particles attractive for a wide range of technologies. However, colloidal particles on the other hand can potentially be harmful for humans and environment.

Dissociation coefficients of protein adsorption to nanoparticles as quantitative metrics for description of the protein corona: A comparison of experimental techniques and methodological relevance.

Protein adsorption to nanoparticles is described as a chemical reaction in which proteins attach to binding sites on the nanoparticle surface. This process is defined by a dissociation coefficient, which tells how many proteins are adsorbed per nanoparticle in dependence of the protein concentration. Different techniques to experimentally determine dissociation coefficients of protein adsorption to nanoparticles are reviewed.
